Rabbi Yoel Sirkis "the Bach" writes in his approbation to Shaar HaShamayim: "I lift my eyes and see a holy and awesome man speaking from within the fire, drinking holy waters from a holy source, flowing from holy channels of the Holy of Holies, quenching those who thirst and yearn for holy matters - none other than the great Rav in all of Torah, the Gaon Rabbi Yeshaya HaLevi z"l... He left behind blessing in his holy works, and when we saw and read them, we felt the influence of holiness from the highest levels in all our limbs, and this is the sign that his works are composed for the sake of Heaven..."

Rabbi Yaakov of Lublin, father of Rabbi Heschel of Krakow writes in his approbation: "The famous needs no proof, for he was a distinguished Rav, a prince in Israel, great was his name and holy shall be said of him... that the Gaon Rabbi Yeshaya Segal z"l Horowitz composed."

The "Tosafos Yom Tov" in his approbation: "...Pleasant words that the Rav, the Gaon, the famous Chassid Rabbi Yeshaya composed... for indeed he is a holy and awesome man whose light of Torah shone previously in Israel... for without doubt a spirit from above was emanated upon him, as was testified from Heaven..."

The "Maginei Shlomo" (grandfather of the "Pnei Yehoshua") writes: "...And as Hashem sent before us one holy person speaking matters that are the secrets of the world, for fiery speech emanates from his mouth and sparks of fire emerge from his mouth... and the holy Chassid, the Gaon z"l opens for us the gate of prayer... and showed without doubt that from the power of his piety and pure fear [of Heaven], as all his deeds were for the sake of Heaven as is known to all our people, and elaborating on this is unnecessary, he merited all this..."
